    The cost of the electricity is FAR from negligible. Ignoring the extra weight of carrying empty or partially discharged batteries (used petro fuel is gone overboard), a kilowatt of electricity costs about 13.9 cents in the US. A gallon of gasoline provides about 34 kW of energy in actual use. (The best lithium batteries are about 90% efficient under ideal charging and discharging conditions). So we do that math: 34 kWh of output from a battery requires about 37.5 kWh of electricity IN to charge the battery. Multiply this by 13.9 cents per kWh and you get is bit over $5.25 per equivalent of 1 gallon of gas. Aviation gasoline averages $4.73 in those same areas. Saying that savings are being made by not purchasing gas, while asserting that the electricity cost is negligible is just wrong. The electricity costs 10% MORE than the gasoline that does the same job.

      At 12:24 you say "fuel costs would be almost entirely eliminated." Nope. The fuel costs go up. Electricity costs more than gasoline in nearly all markets. (Most electricity is still made by burning petro fuels so it has to cost more.) Most trains in the US burn diesel fuel to generate electricity to run the electric motors to propel the train. And you will need more than just propulsion electricity. You will also need electric heaters to keep the plane, its batteries and the passengers from freezing.

    electricity is not free, not even close. The plane for Eviation is rated at 815km of range with a 980kWh battery so if they operate their 1365 flights and assuming they go perfectly in a straight line and never consume any more then the rated power they will travel 1365 times 250km while requiring at least 1.2kWh per km which ends up being ~410.000 kWh of electricity. Now they question is how much are they gonna pay for it given that they not only need much but they also need to fast charge so we can safely assume it will be more expensive then residential prices lets just go with 30 cents/kWh and we end up with roughly $123.000 in electricity cost AT BEST. that is hardly even close to be zero. Sure its a saving if we assume everything else is equal but we also know its not so the math changes quite a bit.

    I hope you don't think they are going to carry batteries. Apart from those things being fucking insanely heavy compared to kerosene, which would make the plane barely flyable, I would like to remind you of the tesla cars that spontaneously start to burn. And to top it of. Electric aircraft fly on fossil fuel you have to keep open only transferring the problem from the airplane to the powerplant which is even more stupid because an electric airplane would require far more energy for the same route. Here an idea for short range travel. Use a fucking train!

    I love how everything electric is sooooo great and has 0 carbon emissions. Yaaaaay. When taking in consideration how the electricity is produced most electric cars use about 3 litres of petrol equivalent per 100 kilometers. I'm not sure if I get it but that's not 0, that's not even a lot less than what many normal cars do.

    if the goal is global net reduction of carbon dioxide production, focus on the "global" aspect and lowest hanging fruit. Reduction of these emissions where battery density is not a primary design constraint would be a good start. Considering reduction in surface travel 10% would probably reset the Carbon clock 15 years.

    12:25 electricity is so cheap its cost is negligible so you just go ahead and eliminate all the cost ????? REALLY ?????? how the hell do you know that you have no specifics how much the electric plane will consume . this is quite literally the worst video you have ever created . in electric cars the cost for traveling a 100 km is roughly 40 percent cheaper compared to petrol and 10 - 20 percent cheaper than diesel if you are slow charging at home . however if you are fast charging you pay double per kwh on average which makes electric cars the most expensive . Now knowing all this information how do you decide to just eliminate 844000 dollars yearly fuel cost the least you could have done is maybe half the number or something . also you did not address the problem with battery degradation and the cost involved in exchanging them is the battery going to last a couple years or maybe you go through a couple batteries every year whatever the case the cost for batteries absolutely needs to be considered because it might be a huge expense . But no this video is just a big ol happy utopia where electricity is free and we have magic batteries ... what a complete joke

Smaller size , higher energy-density , greater durability , and far shorter turn- around times (Roll-on-Roll-off batteries) would all help electric airplanes to operate on a competitive basis , within the short-range transport industry . *Ref.: dragonflyenergy.com/solid-state-battery ^ Scroll down to "Benefits of Solid-State".

    The amount of people here taking a dump on electric transport and batteries is pretty sad actually. Instead of immediately shutting down this progress, we need to recognize it for what it is... A stepping stone to eventual achievements. As we progress, issues such as price of battery production, range, recharge time, recycling, longevity, etc. will all be addressed. No great technology started off perfect. We can't just accept failure and continue to do things the way we do now simply because we haven't achieved perfection yet.

    Unfortunately the technology isn't even close to making battery-electric really viable. Bjorn Fehrm today came out with an analysis of a theorhetical 19-seat commuter aircraft on a 200nm route. Even accounting for a 56% improvement in battery energy-density he writes: "...instead of 628kg jet fuel, where 320kg gets consumed during the flight, we have a constant 8,847kg battery system. The electric energy is 14.09 times heavier for the maximum range flight for the electric airliner. It’s a devastating difference for an aircraft, making it practically impossible to design an aircraft with any reasonable performance around this excess weight."

    Another reason why airlines might care about "going green" is expected legal obligations. If a country decides to force any business to reduce its carbon footprint to a relatively low amount and an airline is not prepare for such a change, it might go under from all the capital expenditure required to bring their fleet up to the code. Thus "caring for the planet" now allows the airlines to test drive projects, evaluate changes, do research and optimize the transition while the proven but "not green enough" business model is still available as a fallback shall cashflow go awry.

      Another idea that these airplanes could exploit would be batteries being installed and removed by robots. That would enable few optimizations. 1. No need to have the entire aircraft grounded while recharging it or stressing the batteries with fast charge (or a combination of both). Just have the robot swap depleted cells with freshly charged and charge the depleted cells slowly in some warehouse, prolonging their lifespan. Also meshes well with renewable but unreliable sources of electricity - instead of pumping the energy into one set of cells fist (power grid storage) and then from that into another set of cells (the airplane's onboard cells), you can have the cells as a part of the smart grid, being fed with the renewable energy as it is produced and just load them into the airplane as needed. 2. Cells going weak? With this setup you can discover this while charging when the cell is outside of the aircraft so it can be readily swapped with a working one and recycled. No need to wait for the aircraft to land or have it wait while a technician scouts its battery for the flawed cell. 3. Going on a short trip? Put in less batteries than the full compliment, meaning less weight. In fact, the place where the airplane is standing while embarking and disembarking could be equipped with a scale so the robots could immediately know how much weight is going to be lugged around and size the battery accordingly. Load a little extra to account for emergencies and you are all set. 4. The fact that charging is no longer done in the airplane means no need to lug the charger and charging circuitry around. Similar for "cell health monitoring" as now the cells are "discharge only" so the charging part of this logic can also stay our of the airplane. 5. This form of "robot replaceable batteries" could be adopted by the electric vehicles too. That would allow the technology to be developed and polished in this far less demanding context before placing it into the demanding world of airplanes.

      There is another reason: electric aircraft like this could enable routes not possible before. Like connecting mountain towns to the rest of the country. It is prohibitively expensive to build sensible roads or railroads to these places due to the complicated and often treacherous terrain. Classic internal combustion powered airplanes have a problem because the runway they need to comfortably access these places is equally impossible to build (see the Lukla airport which has a runway that is anything but comfortable to access). With Vertical Take Off and Landing it would be easier but swinging an internal combustion engine around to allow this would make the already complicated design even more complicated (you know, all these high pressure fuel hoses and stuff like that). On the other hand the super simple electric engine with equally simple power cables could accommodate the VTOL much easier. This means no complicated runways needed, just a flat place with size not that much bigger than the airplane itself. With the airplanes being relatively small (and thus also light) it could be built right on the roof of the airport building.

    As much as Would like planes to go electric, I doubt that will ever work. Bjorn Fehrm explains it very well. In short, batteries are so heavy that the takeoff and range performances suffers too much. Adding batteries doesn't help as the airplane weight goes beyond its capabilities. We would need battery technology to be 5x or 10x more performing (5x to 10x more energy for same weight). When would that be possible, if ever? leehamnews.com/2021/07/08/the-true-cost-of-electric-aircraft-part-2/?.it&

    I do not think the business case is that strong. If you must ground your plane for an hour because it must recharge. The business case goes away. A TBM 930 has a range of 1500+ miles. Which means they can refuel at night or once a day. That dramatically cuts into the profitability of an electric plane, who has to sit for an hour after a roundtrip.

    Straya will almost never get into electric planes. The nearest airport that has passenger flights from Sydney is either Bathurst or Newcastle, and both are well above 2 hours by train (it's a lot slower than car)

      @catprog yes. which is why this rule will never work here

      Sydney to Newcastle : 88 miles Sydney to Bathurst : 95 miles Gold coast to toowoomba: 113 miles. Sydney to Canberra: 147 miles Bosten to Rockland Mayne : 152 miles Sydney to Parkes 179 miles Our trains are much slower then European

    one things that you should consider is how efficient the energy being used is. If a coal plant in Africa is 40 percent efficient, the electricity being used is roughly that efficient. But, if the jet fuel burned on the plane is 70 percent efficient, that is better than an electric plane.

    So… I looked up where most of the cobalt for lithium batteries comes from… Yeah, not sustainable. Back to the drawing board.

      Cobalt is being eliminated from batteries, there is less and less every years. It's not a physical necessity, just a stabilizing element. Lithium is very sustainable, one of the most abundant element, it's just not great currently because we don't use a lot so nobody cared, it's less than 10% of the battery.

    You missed a HUGE use being developed by Harbour Air based our of British Columbia. They have been actively certifying one of their aircraft for commercial flights.

    Let's decrease carbon footprint by using electric airplanes 🤔 Digs deep trenches using heavy duty diesel based equipments to extract lithium for all those extra batteries in demand 🤡🤡🤡

      @catprog where would you get all that huge amount of energy needed for heavy duty machines to dig holes?

      Why use diesel and not electric to get the lithium?

    ...well lets see what he came up with to defend reinventing the wheel instead of switching to the ideal fuel - liquid hydrogen! And nope, nothing. Instead video devolves into promoting vaporware sellers. Yes, looking at eviation alice. That thing - even at a glance - is TERRIBLE design. And to put it bluntly, if you are using heavy propulsion mechanism, you need every tiny edge in efficiency you can get, just to fly. ...take a look at those wingtip mounted engines. ...yes. Well if you have some minor familiarity with aerodynamics, you know that vortices created on the wingtips when pressure difference between the top and bottom of the wing equalizes, create a LOT of drag. Well its great idea to minimize them, or even make them disappear. Thus you put engines turning the opposite direction to the vortice's swirl. Sadly the "wingtip flow laminator" is as viable as plugging an extension cord into itself and hoping for infinite power. Not at all. As the pressure differential persists between the top and bottom of wing. All you achieved is contrarotating the middle of the vortex, while the outside goes into the original direction, basically you managed to be even more wasteful with energy. Now that we are past eviation vaporware... ...lets consider electric aircraft. The issue is weight. As you need to spend energy to keep weight flying. And if your fuel is heavy, that reduces your flighttime and payload BRUTALLY. Extreme short haul flights could be viable on battery power. However those are the realm of general avaition, not passanger airlines - due to things like safety checks taking up more time than the flight itself. What i don't get is why ignore hydrogen. Its as carbon neutral as batteries. You can refit jet engines to run on it. Its colder than current aviation fuel, thus it can cool the jet engine better, thus you can run the jet engine hotter, thus you can run it more efficiently. Its also lighter than current aviation fuel, thus you carry less "dead weight" thus you need smaller wings, thus you attain less drag. The ONLY downside of hydrogen, is costing more than petrocarbon fuels, that require so little pre-processing that it may be nonexistent (at least compared to hydrogen).

    I live in Australia which has a lot of small regional airports and I've been thinking about this for the past two years. I personally hope some of the Australian based startups get in on the electric aviation production game.
